Application January 2, 1948, Serial No. 209

3 Claims.

This invention relates to a means for sharpening knives and has particular reference to a knife sharpening kit.

The principal object of the invention is the provision of a base on which knife sharpening blades are angularly positioned relative to each other, whereby the knife to be sharpened can be manually turned in a simple operation to quickly, easily and effectively sharpen each side of the cutting edge of the knife blade.

A further object of the invention is the provision of means for detachably holding the knife sharpening media or blades, whereby the blades can be readily replaced after the same have become worn.

A further object of the invention is the provision of a device of the character described that is simple in construction, economical to manufacture, strong, durable and highly efiicient and serviceable in use.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is an end elevation of one of the supports for a blade,

Fig. 2 is a perspective view disclosing the blade supports angularly positioned on a suitable base,

Fig. 3 is a top plan view of the base and the supports mounted thereon, and

Fig. 4 is a top plan View of a package for the replacement blades, the view being partl broken away to illustrate the blades in the package.

In the accompanying drawing wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 4 designates a substantially rectangular base on which the supports for the blades are angularly positioned. Since both supports are of similar configuration, but one will be described. Each support comprises a pair of oppositely disposed metal plates 5 and E that are angularly secured to the base 4, by screws or similarly fastened elements 1. A vertical extension 8 is hingedly secured as at 9 to the plate 5, while a similar extension I0 is hingedly secured as at H to the plate section 6.

It will be noted that, as disclosed to advantage in Fig. 1, the said extensions are spaced one from the other as at l2 to permit the insertion therebetween of a blade i 3 which has an upper serrated or knife sharpening top or surface M.

A pair of bolt and nut connections l5 and I6 serve to connect the extensions 8 and I0 one to the other, and the tightening of the nuts on the bolts provide an effective means for gripping the blade to prevent accidental displacement of the same when the blade is in an operative position.

I propose to sell replacement blades in pack-age form so that when the serrated edge of one blade has become worn, it can be replaced by the simple expediency of removing a new blade from the package l1. Then by unfastening the bolt and nut connections the old blade can be removed and a new blade can be placed in its operative position between the extensions 8 and I0.

In the specification I have used the expression knife sharpening kit because I intend to sell the article in the trade as follows: The base with a set of blades mounted thereon will be sold as one unit and the package of replacement blades as a second unit of the kit. It is obvious that as new sets of blades are needed the packages can be purchased in the open market.

In practice the base is placed on a suitable support. Then a wiping contact of one side of the area of the knife to be sharpened, with one of the supported blades, will cause a sharpening of the knife edge. By the simple expediency of bringing the opposite side of the knife edge into contact with the other angularly positioned blade, a sharpening of the knife will be efiected.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. In combination with a base, a pair of knife sharpening serrated blade supports positioned on the base, the said supports being spaced apart and angularly positioned relative to each other, and fastening means for securing the supports on the base.

2. In combination with a base, a pair of knife sharpening blade supports angularly positioned thereon, each of said supports comprising a pair of plates fastened to the base and spaced one from the other, a vertical extension carried by each of said plates, and fastening means conmeeting said extensions one to the other for gripping the knife sharpening blade.

3. In combination with a base, a pair of knife sharpening blade supports positioned on the base, each of said supports comprising a pair of plates secured to the base and spaced thereon one from the other, a vertical extension hingedly secured to each of said plates, and fastening means connecting the extensions for gripping the latter between the knife sharpening blade.
